EDWARD J. GELLENBECK, or Sl-IAKOPEE, MINNESOTA, AssIe oR OF ONE- HALF TOHERBERT A. ZETTLE AND MATHIAS A. DEUTSCIAI, or SAME PLACE.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 613,879, dated November8, 1898. Application filed May 29, 1897. SeTialNo. 638,680.(1101101191.)

T aZZ whom it may concern:

Be it known that I, EDWARD J. GELLEN- BECK, of Shakopee, Scott county,Minnesota, have invented certain Improvements in Acetylene-GasGenerators, of which the fol lowing is a specification.

My invention'relates to improvements in acetylene-gas generators; and itconsists in the features of construction hereinafter particularlydescribed and claimed.

The accompanying drawing, forming part of this specification, shows avertical crosssection of my improved apparatus.

In the drawing, A represents the holder, having the water-receptacle 2,the bell 3 working in said receptacle and guided in its verticalmovement, as actuated by the inclosed gas, by means of the rod 4,working in eyes pr guides 5 upon the outer wall of the recepac e 2.

6 is a water-inlet pipe by means of which the supply of water may bemaintained in the gas-holder.

7 is the gas-outlet pipe, provided with suitable stop-cock 8 anddrainage-cock 9.

10 is the gas-inlet pipe,having, preferably, a flaring mouth or bell 11,normally standing beneath'the surface of the water 12-, so as to washthe gas as it enters the gas-holder.

13 is a movable Valve or plug in the top of the bell, to permit theescape of air when the bell is set in place.

B is the generator, made up of the water receptacle 14 and the bell 15,standing in and sealed by the water thereof. This bell is preferably setso as not to move in use by means of spring-catches 16, which supportthe bellin its normal position, but which can be sprung back out ofengagement with the bell, so as to descend when it is desired to expelall the inclosed gas.

17 is a 'movablevalve or plug for permitting the escape of air when thebell is set in place. i

18 is the water-inlet pipe, by means of which the water-receptacle 14can be charged with the water 20.

Arranged in the generator is the carbidbasket 21, having an open top andopen-work 5o sides and bottom. The basket is provided with a verticaltubular opening 22 therethrough surrounding the gas-outlet pipe 23,which is connected with the pipe 10 in the gas-holder and is providedwith a suitable drainage-cock 24. The top of the pipe 23 stands normallyopen to permit the gas to pass from the generator to the gas-holder, butmay be closed by the valve 25, actuated by the valve-stem 26 and handle27. The valve is closed whenever it is desired to recharge thegenerator. The closed top pipe 28, extending through the center of thebasket and fixed thereto, is adapted to receive the stand-pipe 29, fixedto the bottom of the waterreceptacle, through which the rod 30 extendsto the top of the pipe 28. This rod is pivotally connected to andsupported upon the lever 31, which is pivoted on'a double hinge 32to thebottom of the generator, its power-arm 33 carrying a weight 34. Theother end of the lever is pivotally connected to the rod 35, havingadjustable stops 36 and 37, between which stands the rod 38, carried bythe bell of the gas-holder. This rod 38 slides freely upon the rod .35between the stops and serves to actuate the rod when it strikes eitherof the stops, so as to operate the lever 31-, and thereby either raiseor lower the carbid-basket to partially submerge or lift it above thewater in the generator, so as to set the generator in action or stop thegenerating of gas automatically as the bell 3 rises and falls. Thedebris can be removed from the generator through the drainage-valve 39.

40 is a dome upon the top of the bell 15, which serves to receive thetop of the pipe 28 when the bell is thrust downward, so as to entirelysubmerge the carbid-basket to force all of the inclosed gas out throughthe pipe 33.

To set the apparatus in operation, the gas holder and generator are bothsupplied with water to the levels indicated in the drawing. The valve 13in the bell 3 is then opened to allow the escape of the inclosed air andpermit the bell to descend to the bottom, when the valve is closed. Thebell 15 is then removed from the generator, and the basket is suppliedwith carbid. The bell being then returned to place and the valve 17opened, the inclosed air is permitted to escape, and

the bell is pushed downward, so as to force all of the included air out,and when the gas has generated from the carbid it can be lifted intoplace and secured byits spring-catches. The gas then flows from thegenerator through the pipes 23 and into the gas-holder, the bell 3 beinggradually lifted until the rod 38 strikes the stop 36, thereby liftingthe rod 35 and operating the lever 31, so as to gradually lift thecarbid-basket out of the surrounding water, thus checking the generatingof gas, the outflow of gas from the gas-holder being controlled by itsstop-cock 8.

When it is desired to recharge the generator, the spring-catches 16 aredisengaged from the bell and the bell pressed down until the gas isentirely expelled from the generator, when the valve is closed. The bellis then lifted out of the generator and the basket recharged, the bellbeing restored in place in the manner above described. The valve 25 thenbeing opened, the operation is proceeded with.

I claim 1. In an apparatus of the class described, the combination withthe gas-holder, of the generator consisting of the water-receptacle, thebell arranged therein and sealed by its contained water, thecarbid-basket arranged within said bell, and the water seal consistingof a pipe opening through the bottom of the water-receptacle of thegenerator and telescoping into said carbid basket, and the meansoperated by the bell of the gas-holder for raising and lowering saidbasket.

2. In an apparatus of the class described,

the combination with the gas-holder, of the generator consisting of awater-receptacle, the carbid basket arranged therein, the pipe openingthrough the bottom of the receptacle and telescoping into thecarbid-basket to form a water seal, the rod extending through saidwaterseal pipes, and the means actuated from the bell of the gas-holderfor raising and lowering said rod to carry the carbid-basket into or outof the water.

3. In an apparatus of the class described, the gas-generator, comprisingin combination the water receptacle, the bell adjustable therein andsealed by its contained water, the means for securing the bell in normalposition, the carbid-basket arranged within said bell, the stand-pipearranged in said holder to permit the outflow of gas and projecting intoand through a vertical opening in said basket, the valve for closing thetop of said stand-pipe, the centrally-arranged stand-pipe in saidgenerator, opening through the bottom of the water-receptacle, andtelescoping into the closed pipe in said basket, the rod extendingthrough said stand-pipe and to the top of said closed pipe, the leverfor reciprocating said rod, and the operating connections between saidlever and the bell of the gas-holder, whereby the carbid-basket iscarried into or out of the water automatically by the rise and fall ofthe bell of the gas-holder.

4. In an apparatus of the class described, the combination with thegas-holder A having a hell 3, and the generator B having the bell 15, ofthe spring-catches for supporting the bell 15 in normal position, thecarbid-basket arranged therein, the stand-pipe 23 arranged in saidgenerator and provided with a valve 25, the stand-pipe 29 working in anopening in the basket, the rod extending through said pipe 29 and to thebasket, the lever 31 connected to said rod and serving to actuate thesame to raise and lower the basket, and the opera-ting connectionbetween said lever and the bell 3, whereby the rise and fall of the bell3 serves to automatically raise and lower the basket.

5. In an apparatus of the class described, the combination with thegas-holder, of the gas-generator, comprising in combination theWater-receptacle, the bell adjustable therein and scaled by itscontained water, the earbid basket arranged within said bell, thestand-pipe in said generator opening through the bottom of thewater-receptacle and telescoping into a closed pipe in said basket, therod extending through said stand-pipe and to the top of said closedpipe, the lever for reriprocating said rod, and the operatingconnections between said lever and the bell of the gasholder, wherebythe carbid-basket is carried into or out of the water automatically bythe rise and fall of the bell of the gasholder.

In testimony whereof I affix my signature in presence of two witnesses.
